Shield State This section describes the Shield state in the MegaRAID Storage Manager software. Physical devices in the MegaRAID firmware transit between different states. If the firmware detects a problem or a communication loss for a physical drive, it transitions the physical drive to a bad (FAILED/UNCONF BAD) state. To avoid transient failures, an interim state called the Shield state appears before marking the physical drive as a bad state. The Shield state is an interim state of a physical drive for diagnostic operations. The results of the diagnostic tests determine if the physical drive is good or bad. If any of the diagnostics tests fail, the physical drive will transition to a BAD state (FAILED or UNCONF BAD). The three possible Shield states are Unconfigured - Shielded, Configured - Shielded, and Hotspare - Shielded.

Shield State
This section describes the Shield state in the MegaRAID Storage Manager software.
Physical devices in the MegaRAID firmware transit between different states. If the firmware
detects a problem or a communication loss for a physical drive, it transitions the physical drive to
a bad (FAILED/UNCONF BAD) state. To avoid transient failures, an interim state called the Shield
state appears before marking the physical drive as a bad state.
The Shield state is an interim state of a physical drive for diagnostic operations. The results of the
diagnostic tests determine if the physical drive is good or bad. If any of the diagnostics tests fail,
the physical drive will transition to a BAD state (FAILED or UNCONF BAD).
The three possible Shield states are Unconfigured - Shielded, Configured - Shielded, and
Hotspare - Shielded.
